CARPET-#STRETCH ER.

SPECIFICATION forming part of Letters Patent No. 772,945, dated October25, 1904.

Application filed March 15, 1904.

To all whom/ t may concern:

Be it known that I. J EREMIAH H. LYNCH, a citizen of the United States,residing at Rock Valley, in the county of Siouxv and State of Iowa, haveinvented new and useful Improvements in Carpet-Stretchers, of which thefollowing is a speciiication.

This invention relates to carpet-stretchers, and more particularly tothat class of carpetstretchers embodying longitudinally-extensible rodsor bars anda lever to cause moveyment of the bars with respect to eachother.-

The object of the invention is to construct a carpet-'stretcher of .thisgeneral character which will embrace the features of simplicity ofconstruction and operation, strength with lightness, wide range ofadjustment, and compactness when taken apartfor storage.

In the accompanying drawings, Figure 1 is a longitudinal section of acarpet-stretcher embodying my improvements. Fig. 2 is. a top plan viewthereof, the operating-lever being shown in section. Fig. 3 is a`transverse section taken on the dotted line 3 3 of Figs. 1 and 2. Fig. 4is a transverse section taken on dotted line 4 4 of Figs. 1 and 2. Fig.5 is a transverse section taken on dotted line 5 5 of Figs'l and 2.

On the several figures of the drawings like parts are correspondinglymarked by characters of reference.' Y f The main body A of the stretcheris a troughshaped frame formed of a bottom 1 and sides 2 and 3, arrangedparallel to each other and at right angles to the bottom. The upperedges of the sides2 and 3 are provided with inclined notches 4, roundedat the base and arranged in pairs, so that the notches of the side 2will be in line with the notches of the side 3, as

Serial No. 198,288. (No model.)

of the lbody A, and within a crotch 7 at itsiforward end is pivoted oneend of a link 8,t he other end of which is pivoted Within an elongatedslot near the lower end of the operating-lever C. Below the slot withinwhich the link 8 is pivoted the lever is provided with across-pin 9,constituting a journal to engage the respective pairsof notches 4 in thesides 2 and 3 of the body A. f The lever extends slightly below theAcross-pin 9, and is of a width to fit between the sides 2 and 3,- thuspreventing sidewise movement of the lever and preventing lateral strainbetween lthe lever and link 8. The opposite end of the extension-bar Bis reduced in height and terminates in a iiat surface 10, to which issecured two or more guide-loops 1l 12 to receive and hold one end of ananchor-bar D, the other end of which (or an extension thereof) isdesigned to rest against the washboard of a room in operation or someother suitable abutment.

The stretcher-head E is a T-shaped structure comprising a cross-bar 13and shank 14. The cross-bar is tted on its lovvggerV surface with spikesor claws 15, adapted to engage the fabric o f a carpet, and the shank isof a width to iit snugly within the way formed by the grooves 5 of thebody A, as shown in Fig. 3,

.whereby the stretcher-head is iirmly secured to the body A, but may beremoved by drawing the shank 14 from the grooves 5 when occasion demandsfor purposes of storage, Sac.

To one side of the extension-bar B is pivoted a gravity-pawl 16, adaptedto engage the notches of the side 2 of the body A, and thereby hold theextension-bar against the stretcherhead.

The anchor-bar D may be made in one or more sections to suit the needsof purchasers.

As shown, it is constructed of two slidablyengaged sectlons maintamed 1noperative relation by'guide-loops 17, secured to the outern j'ustrnentas to length of the stretcher as a Whole. Y

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent of the United States, is

l. In a carpet-stretcher of the character described, the combination oithe body having grooved sides, the edges of which are notched, thestretcher-head, the extension-bar slidably mounted in the grooves of thebody, a lever having a cross-pin for engagement with the pairs ofnotches of the body, and a link pivoted to the lever and to theextension-bar, guide-loops carried by the extension-bar, and ananchor-bar secured removably in said loops, said anchor-bar beingconstructed of sections adjustable longitudinally on each other.

2. In a carpet-stretcher of the character described, the combination ofthe body having' grooved sides, the edges of which are notched,

Vthe extension-bar slidably mounted in the grooves of the body, a leverhaving a crosspin for engagement with the pairs of notches l ot' thebody, a link pivoted to the lever and to the extension-bar, and thestretcher-head having its shank removably mounted in the grooves of thebody.

3. Ina carpet-stretcher of the character described, the combination ofthe body having vertical sides notched at their edges, the extension-barslidable between .said sides, a lever having a cross-pin to engage thenotches of the sides, a link connecting the lever and extension-bar, anda stretcher-head; said lever extending` below said cross-pin and of awidth to lit between the sides, whereby sidewise movement of the leverand lateral strain between the lever and link are prevented.

In testimony whereofl have signed my name to this specilieation in thepresence of two subscribing witnesses.

JEREMIAH ll. LYNCH.
